Application filed November 4, 1907. Serial No. 400,701.

To all whom it may concern:

Be it known thatI, OBLA'N S. LEE, a citizen of the United States,residing at You stown, in the county of Vigo and State of ndiana, haveinvented a neyv and useful Improvernent in Dish Washing Machines, ofwhich the following is a specification.

My invention relates. to improvements in dish-washing machines in whichstreams of water from a pump operate in conjunction with revolving dishtrays.

Figure I. is a side elevation. Fig. II. is a top view. Fig. III. is avertical cut section on the line, a: a: lookin in direction of arrow,II. Fig: IV. is a vertical cut section on the line a 0 looking in thedirection of arrow Fig. II. Fig. V. is a view of a horizontal cutsection on the line b 5 looking in direction of arrow Fig. I. with thetube extended. Fig. VI. isa detail top view of gear.

The cylindrical tank 1. constitutes the body of the machine to which issecured the pump cylinder 2. The lower head 3 of the pum cylinder 2 maybe integral with or secure to the cylinder in'any suitable manner.

' The upper head 4 of the c linder 2 fits over side of the tank 1. saidtube is the to of the cylinder an is retained in position ymeans ofbolts 55 Fi I. assmg through lugs 6666 into a wit cylinder heads. Theupper cylin or head 4 has reared from two diametrically op osite pointson its upper surface two upward y extending arms 7 and 8 Fig. III. whichextend a predetermined distance above the top of the tank 1. so that thecrank shaft 9. when mounted in the bearings 1112 at the extremities ofsaid arms will be in alinement with the horizontal shaft 13. Fi II. Toarm 8 is secured the ide 14 wit the eye 15 of said guide immeiatelyabove-the center of the cylinder 2. The piston rod 16 passes through theeye 15 of the guide 14 through the stuffing box 17 and is secured to thepiston 18 in any suitable manner. A pitman 19 is pivotally secured atits ends tothe piston rod 16 and the crank portion 10 of the crank shaft9.

The tube 20 shown in Figs. I. II. and V is closed at its ends and issecured to the outrovided with which open s 22 and 23 connect the aseries of perforations 21 Fig. into the tank 1. Pi

upper and-lower on s of the cylinder with the tu e 20. Said pipes arerovided with valves mit ofthe passage of water from the cylinder 2 intothe tube 20 and prevent its return flow. Pipes 26 and 27 connect the upor and lower end of the c linder 2 with t e tank 1 and are provide withvalves 28 and 29 which ermit of the passage of water from the tan k 1.into the cylinder 2 and prevent its return.

It is evident that the revolution of the crank shaft 9 will produce anoscillating movementof the piston 18 and a consequent movement of waterfrom the tank 1. through the pi es 262722 and 23 and cylinder 2 into t etube 20 through the perforations 21 back to the tank 1. In order tosecure more uniformit of pressure on the water in the tubes anconsequently more uniformity of flow through the perforations a tube 30connects at its lower end to tube 20 and has its ends closed forming anair bulb.

It is desired that streams of water ma be brou ht in contact with thedishes from a ove and elow. To rovide for this a horizontal tube 31 Fig.1K and V connects near the bottom of the tank 1. with the tube 20; saidtube extends a suitable distance toward the center of the tank 1. It isprovided with a series of perforations on its upper side and has itsinner end closed. A horizontal tube 32 having its inner end closed isprovided with a series of perforations on its under side and is hingedto the upper end of tube 20 so.

that it may be turned upwards and outward to (position shown in dot FiV. To the free en of the tube 32 is secure an eye 33, which is designedto pass over the upper end of the pe endicular shaft 34 therebyretaining said sha t in position. In order that the eye ma 33 readiypass over the upper end of sh t 34 said s a t is slightly beveled at itsupper end and the socket 36 is sha ed like an inverted cone which willrovi e for sufficient lateral movement of SE8? 34. Means are provided tobring the dishes in contact with the streams of water. coming from theper-' forations. 7

The perpendicular shaft 34 Fig. III. and V.- having the horizontal arms35-35-3535 secured thereto is rotatably mounted within the tank 1. bymeans of a socket 36 in the center of the bottom of the tank 1. whichforms a bearing for the lower end of the shaft 34. The upper end be a edlater described. A dish tray 3 is supdjustabl mountported on the arms3535-35 35 from the shaft 34. Said trays are constructed of wire and arecircular with a diameter a little less than the diameter of the tank 1.so that the shaft 34 and trays 37 may be revolved without co in contactwith the sides of the tank 1. e bottoms of the trays are convex, and areprovided with openings at their centers ada ted to pass over the shaft34 Fig. III, e ear 38 is slidably mounted on the up er on of shaft 34 bymeans of sutures 39. 'g. VI. in said gear interlocking with similarsutures on said shaft. The lower hub- 40 of the gear 38 is mounted in acircular o ening in the center of the lid 41 of the-tank and the upperhub 42 is similarly mounted in the bar 43 secured to the lid 41 Fi II.Said lid is hin ed to the tank '1. anIl when .it is o ned sai gear isretained in its osition on t e lid 41 but the sutures 39 of t e gear 38and shaft 34 disenga e. Said filer sliding off of the beveled end 0shaft 34.

a. horizontal shaft 13 is rotatably mounted in the bea s 4444 Fig. II.and is in alinement with crank shaft 9 with the screw 45'integral withsaid shaft 13 in engagement with the gear 38. Theerank shaft 9terminates at its outer end in the crank 46. The inner end of shaft 9 isrecessed forming a slot 47 III. ada ted to admit the flattened end 51 ofthe s 13 fo which serves to transmit motion romthe crank shaft 9 to theshaft 13 and also to pera joint mit of the free movement of the hinge 48of the lid 41 when said slot assumes a vertical claim as new and desireto secure by Letters Patent is,

The combination in a dish-washing ma- 4o chine of a tank, a verticalshaft rotatably mounted within said tank, horizontal arms on said shaft,a circular dish tray su ported on said arms, a ump and erforate outlettubes providing or a plura ty of streams of water from said pump to"said tray with means for operating said pump and revolving said verticalshaft in con unction, said means comprising a horizontal shaft 13rotatably mounted on the cover of said tank, said 50 horizontal shaft,having a flattened end 51 for engaging a slot 47 in a crank shaft 9whereby the revolution of said crank shaft transmit motion to saidhorizontal shaft and provide for the opening of said cover .55 when saidslot occu ies a vertical position, a screw gear 45 onsai horizontalshaft engaging a gear 38 centrally mounted in said cover and, sutures insaid gear for engaging sutures in the'upper end of a-vertical shaft 34substantially as and for the purpose described.
